JOSEPH D. SMITH, OF ROCKFORD, ILLINOIS lM PROVEMENT IN STUMP-EXTRACTORS.

Specification forming part of Letters Patent No. 204,627, dated June 4,1879; application filed April 30, 1878.

To all whom it may concern Be it known that I, J OSEPH D. SMITH, ofRockford, in the county of Winnebago and State of Illinois, haveinvented certain new and useful Improvements in Stump-Extractors; and Ido hereby declare that the followin g is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form part of thisspecification.

My invention relates to stump-pullers; and it consists in certainimprovements upon Letters Patent No. 201,297, granted to me March 12,1878, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionppertains to make and use the same, I will now proceed to de scribe itsconstruction and operation, referring to the annexed drawings, in which-Figure l is a plan view of my improved stumppuller. Fig. 2 is a sideelevation of the same. Fig. 3 is a perspective view of the inner end ofthe sweep. Fig. is a similar view of the center portion of the sweep.Fig. 5 is an enlarged detailed section of a part of the frame.

A represents the bed-piece or platform, secured upon sills A A, whichhave wheels or rollers a a mounted in mortises near their ends. At therear end of the platform A is a crossbar, A to which the cap ortop-plate B is secured. The front end of the cap B is supported by meansof tubes or sleeves G 0, through which bolts or screws C C are passedfor connecting the cap to the platform. The lower end of each tube orsleeve 0 is turned down, as shown at b in Fig. 5, to form a bearingforthe side roller D. D is the center roller between the rollers D. E isthe large cogwheel on the shaft, with sprocket-wheel F, and G is thecog-wheel, to the shaft 01 of which the power is applied. These wheelsare all constructed and arranged in the same manner as described in myformer patent above referred to. The cap B is braced to the platform Aand sills A by means of braces e e, substan tially in the manner shown.To the upper end of the shaft (1 is secured a flanged casting, H, on topof which are firmly bolted two bars, I I, forming the sweep. The outerends of these bars are brought together, fastened by bolts, and providedwith a suitable clevis for attaching the team. About midway on top ofthe sweep is secured a plate or casting, K, which hasdownwardly-projecting side flanges k k, fitting between the two bars II, and acting as central braces for the sweep. At each end of the plateor casting K is an upwardly-projecting crotch, 7a, to receive and holdthe bar J, the front of which is to be attached to the collar of thehorse. The inner end of this bar J is pivoted to a rod, f, which isswivelcd in the center of the plate K, so that the bar J can easily beturned over or swung around from one side to the other. L represents thepulley, mounted in a frame, M, and said frame secured to a bar, N, inthe same manner as in my former patent. In the present case I extend theframe M in the rear, and provide the same with an upright shaft orroller, h, provided with a suitable eye, 1?, to receive a lever forturning the same. I also provide said shaft or roller with aratchet-wheel,i,into which takes a pawl, R, pivoted on the frame M. Tothe shaft h is attached a rope or cable, m, the other end of which is tobe anchored at any suitable distance from the machine. S is the chain,which passes around the sprocket-wheel F, and its ends between thecenter roller D and side rollers D D. In my former patent this chainalso passed around the pulley L in the frame M, and said pulley-framehad at all times to be anchored at the same distance from the machine.This is oftentimes inconvenient, and I sometimes impossible to do; andto obviate such difficulty I attach to one end of the chain S a strap,cord, or cable,V, and this is passed around the pulley L, and thenfastened by a hook to any link desired in the chain, leaving one end ofthe main chain free to be placed around the stump, or for the attachmetnof other chains, as may be desired. This, in connection with the rope orcable on and windlass on the pulley-frame M, admits of anchoring themachine in any place and of using a comparatively short chain whereotherwise a very long one would be required.

It will be noticed that, when the cord or cable Vis attached asdescribed, there is nevertheless an endless connection between thesprocket-wheel F and pulley L, just the same as in my former patent.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The shaft h, with eye I, ratchet-wheel i, a d pawl R, in combinationwith the pulley L, pulley-block M, and bar N, for the purposes hereinset forth.

2. The combination of the pulley-frame M, pulley L, Windlass h P, pawland ratchet i R, able m, and chain S with cord or cable V,

for the purposes herein set forth.

3. The plate or casting K, with side flanges k; k, and end crotclies kk, in combination with the sweep I 1, bar J, and swiveled rod f,substantially as and for the purposes herein set forth.

4. In combination with the platform A and cap B, the shouldered sleevesO, pulleys D, and bolts or screws 0, substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.
